About

I'm Gi, a hairstylist at Alt. Alchemy in Marlboro NY. From my humble beginning cutting friends’ hair in college to working on photoshoots and film shoots, my mission has remained the same: help people step into their full expression with confidence! I offer completely personalized and creative haircuts, colors, and styles designed to fit your hair type, lifestyle, and individuality. Why the name Tress & Treble? In addition to being a hairstylist, I also work with musicians, offering signature styling for performers who want their visual presence to resonate with the same depth as their artistry. But you don’t need to be a performer to belong here! I welcome all clients from all walks of life who want to feel more aligned with their identity. Let’s celebrate what makes you unique! Specializing in creative haircuts, highlights, and customized vivid colors. Expert Certification in Danger Jones brand color. Logo designed by Shane Keaney Graphic Design
